Tilapia is one of the world's most farmed fish species, with production concentrated in Asia, Africa and Latin America where welfare standards vary significantly.
As a sentient species capable of experiencing pain and stress, farmed tilapia deserve welfare consideration. High stocking densities in intensive systems cause chronic stress as evidenced by elevated cortisol levels and increased disease susceptibility. Poor water quality causes respiratory distress and physiological damage. Welfare-conscious tilapia farming manages stocking density carefully, maintains excellent water quality, uses enriched environments, and applies effective stunning before slaughter. Certification schemes are gradually raising baseline standards globally.
